It is known that the cpufreq can be problematic so the recommended way forward is to currently revert the cpufreq enablement commit commit 3949df6ecdca04339bc8a3925c2ba7f881cf82b1 Author: David Abdurachmanov <david.abdurachma...@sifive.com> Date: Tue Jan 28 02:55:56 2020 -0800 SiFive Unleashed CPUFreq == The fix(es) == Revert commit "SiFive Unleashed CPUFreq" == Test Case == Boot with the latest DT. It should now boot. Boot without the latest DT, it should also boot. == Where problems could occur == 1. Users expecting CPU freq scaling now don't have this working option. This is deemed to be acceptable as without the fix their systems are likely to be unbootable with the updated DT.
